Topic: Soundproofing a home theater (Read 1110 times)

I'm soundproofing a home theater and have some questions. I won't be able to soundproof all four walls. Just two of the walls which I know is already going to greatly reduce the effectiveness of the soundproofing. So I'm trying to maximize the bang for my buck.

1) On one of the two walls I may not be able to treat the theater side of the wall but I can treat the exterior side of the wall. Is there any point to doing this or does soundproofing have to be on the theater side of the wall in order to be effective?

2) What is the limit on combining clips, green glue and MLV? Let's say I can treat both sides of a wall, what is the ideal combination of these three methods? At the extreme it would go drywall:green glue:drywall:clips:mlv:studs:mlv:clips:drywall:green glue:drywall

I assume that this is not ideal. So if you are treating two sides of the wall, what is the ideal combination of these three techniques?

3) Same question but assume that clips are not an option on the theater side of the wall. Then what is the best combination if I can do whatever I want to the exterior side of the wall and I am limited to green glue and/or mlv on the interior side of the wall?

1) treating the exterior would still be some what effective for mid range and high frequencies however the bass (low frequency) is going to flank around the partition and remit at some unknown value.So this area will dictate the weakest point in the system and we will have to asses the value. So I will need more information on the current building structure to determine that value...I will need you to contact me direct for this part of the project.

2) the order in which this is built is one of our most ideal systems for shared walls and it does deliver an amazing value of reduction across the band width.

3) clip and channel on the receiving side of the partition is not as effective because the vibration is already in the structure and easily flanks around the floated wall. This would make decoupling hard to justify depending on the building layout.

I am really going to need more detail on the building layout to make these recommendations cost effective.
